4. Review proposed TORs for <strong>SC186</strong> and WG1.<br />
Proposed revised terms <strong>of</strong> reference for <strong>SC186</strong> and WG1 were presented to the<br />
committee. The revisions were agreed to with two editorial changes:<br />
• Need to change WG to <strong>SC186</strong> in last sentence <strong>of</strong> the 186 TORs.<br />
• Update TIS-B MASPS dates in 186 tors<br />
With these changes, both TORs were approved by the plenary. The plenary agreed to<br />
present the <strong>SC186</strong> TORs to the <strong>RTCA</strong> Program Management Committee for<br />
consideration.<br />
There was a discusison as to whether the other working groups in <strong>SC186</strong> should have<br />
terms <strong>of</strong> reference. It was agreed that they should. As such, the plenary requested an<br />
action for all WG chairs to bring back a proposed terms <strong>of</strong> reference to the next plenary.<br />
5. Discussion <strong>of</strong> upcoming changes to standards and message set.<br />
It was agreed to open a discussion <strong>of</strong> finding a more timely path to make changes to our<br />
standards and specifically to the message set as needed.<br />
George Ligler recommended that the plenary establish an ad-hoc group to work out a<br />
multi-year approach to accomplish this objective and avoid having standards lag 3 or 4<br />
years behind where they ought to.
The plenary agreed to establish this ad-hoc group. It was agreed that the group will work<br />
on applying the structure that is already in place with regard to our document waterfall<br />
(i.e., ASA MASPS followed by ADS-B MASPS then link and ASSAP/CDTI MOPS).<br />
The group is actioned to come up with a specific plan to work on the details <strong>of</strong> how we<br />
will proceed.<br />
The group will propose a plan <strong>of</strong> how to apply our process and accelerate as much as<br />
possible the implementation <strong>of</strong> new air-to-air applications.<br />
The plenary agreed to the following membership for this ad-hoc group:<br />
• George Ligler (lead)<br />
• Stu Searight<br />
• Rich Jennings<br />
• Jim Walton / Bob Hilb (alternates for UPS)<br />
• Tom Pagano<br />
• Rocky Stone<br />
• Randy Bone<br />
• Boeing representative (TBD possibly John Brown or Tony Warren)<br />
The ad-hoc group will also make recommendations as to “trigger points” for revisions to<br />
ASA MASPS and the subsequent document water fall.<br />
The group will issue a status report to the plenary in October and will issue a final report<br />
to the plenary in January.<br />
6. SBS Program Status Briefing – Vinny Capezzuto<br />
Vinny gave a status update on the SBS program. Highlights:<br />
• NPRM due out 9/<strong>20</strong><strong>07</strong>.<br />
• Will be moving towards the next phase shortly, as we begin ground infrastructure<br />
deployment.<br />
• <strong>20</strong>13 complete date for ground infrastructure to be deployed.<br />
• Vinny emphasized that the ASSAP/CDTI approval is key to the program.<br />
• PHL IOC 2/<strong>20</strong>10 conflict detection (surface).<br />
• Need to talk about the WG1 OSED for Surface Conflict Detection for June<br />
<strong>20</strong>09… need to make sure that we have an integrated schedule that coordinates<br />
program <strong>of</strong>fice needs with this IOC date.<br />
Vinny raised a concern about the schedule coordination and making sure that WG chairs<br />
are working with the program <strong>of</strong>fice.<br />
7. Working Group Reports<br />
5
• WG-1 – Operations and Implementation (Randy Bone)<br />
Randy reported on progress for the surface alerting application. Jim Duke was<br />
nominated and approved by the plenary to co-chair the ATSA-SURF subgroup. The<br />
current plan is to have the OSED, SPR, and Interop in approximatey 1 and ½ years. It<br />
was agreed that a controller needs to be part <strong>of</strong> the core team for the OSED. A draft<br />
application description is planned to be presented to the plenary in January.<br />
• WG-2 – TIS-B MASPS (Ken Staub) and Final Review/Approval - Proposed<br />
Final Draft – revised DO-286A – Minimum Aviation System Performance<br />
Standards (MASPS) for Traffic Information Service – Broadcast (TIS-B), <strong>RTCA</strong><br />
<strong>Paper</strong> <strong>No</strong>. 158-<strong>07</strong>/SC-186-249.<br />
DO-286A: all responses were concur with comment. All comments were adjudicated<br />
with concurrence from the comment authors. ADS-R: Ken recommended that an <strong>RTCA</strong><br />
publication is not needed as ADS-R is well addressed by program <strong>of</strong>fice requirements.<br />
Ken’s two recommendations were approved by the plenary: (1) The TIS-B revision<br />
cited above was approved to be sent to the <strong>RTCA</strong> PMC as DO-286B. (2) The ADS-R<br />
material will not be published. The ADS-R material will be archived by <strong>RTCA</strong>.<br />
• WG-3 – 1090 MHz MOPS (Tom Pagano)<br />
Gary Furr showed a web site that he has constructed for the plenary and asked for plenary<br />
approval to put committee archival files on the site. The plenary agreed to have Gary<br />
populate the site.<br />
• WG-4/B ASAS MOPS (Don Walker, Sethu Rathinam)<br />
Don presented WG4 progress. An issue <strong>of</strong> concern for which plenary consideration was<br />
requested was the CD application. The working group is concerned that the specific<br />
thresholds in the CD requirements in the ASA MASPS are not sufficiently mature to<br />
make into requirements. The working group discussed options this week, there were<br />
three. Don presented to the plenary the three options with the request that the plenary<br />
endorse one <strong>of</strong> the three; the WG recommendation was for the third option.<br />
1. Drop the CD application<br />
2. Do the required homework to validate the CD thresholds – estimated to be about a<br />
9 month effort<br />
3. Make algorithm performance a requirement based on example scenarios, make<br />
thresholds recommendations in appendices rather than requirements, and let<br />
vendors develop the final design and compete<br />
After some discussion, the plenary endorsed option 3.<br />
6
Sethu reported that the CDTI group has moved to document drafting … 80% <strong>of</strong> draft<br />
material is complete and they are in the process <strong>of</strong> detailed review. Writing should be<br />
done within the next 6 – 8 weeks. The group is holding teleconferenes every 2 weeks …<br />
Sethu felt that the schedule risk for meeting the April target is relatively small.<br />
• WG-5 – UAT MOPS<br />
George Ligler reported that the UAT SARPS will be in an ICAO amendment that takes<br />
effect in <strong>No</strong>vember <strong>of</strong> this year.<br />
• RFG (Roberta Messiah, Jim Baird)<br />
Roberta reported on the VSA and ITP applications.<br />
VSA: The RFG has agreed to an approach to use <strong>of</strong> flight ID and has agreed to a<br />
performance spec based on a comparison with what pilots are doing today.<br />
The status <strong>of</strong> VSA is considered yellow because <strong>of</strong> discussion <strong>of</strong> two versions <strong>of</strong> the app:<br />
basic vs. advanced.<br />
ITP: The OSED is mature and will be moved forward into SPR. The OPA scope has<br />
been agreed.<br />
Jim Baird reported on the RAD application: the comments on the OSED have been<br />
resolved; the OSA and OPA have begun in parallel.<br />
George Ligler presented a paper on 4096 code and asked for plenary agreement that we<br />
remove the geographic filter in DO-260A so that the 4096 code is broadcast outside the<br />
United States. The plenary agreed to have WG3 go work on a change DO-260A to take<br />
care <strong>of</strong> this. WG3 will work towards a January approval.<br />
8. New Business.<br />
<strong>No</strong> new business.<br />
